UK-level Pensioners’ Incomes (PI) Series data is available from 1994/95 to 2018/19 on the Stat-Xplore online tool. You can use Stat-Xplore to create your own PI analysis. The PI information is available at family (benefit unit) level.
Note that regional and ethnicity analysis are not available on Stat-Xplore because multiple-year averages cannot currently be produced. This information is available in the PI data tables.
